Leader lines are typically used as a more durable way to connect air line to the front bags within the wheel well, especially on MacPherson strut suspensions where the entire strut turns with the steering wheel. This 23 inch leader line does not come with PTC fittings so you will need to reuse your existing fittings, or pick up a couple of the SMC DOT Female Straights to mate the leader lines with your existing nylon air line.
